Power preamplifier CRY3503

currentmeasuring1/2" microphone

Key Specifications Frequency Range: 0.6 Hz to 100 kHz (±0.2 dB) Input Impedance: ＞15 GΩ/0.4pF Output Impedance: ＜35Ω Applications Measurements where space is limited For use with prepolarized condenser microphones CRY3503 is a constant current power preamplifier. It can be used with the CRY3000 series 1/2 inch prepolarized measurement microphone and is widely compatible with other brands. CRY3503 converts high input impedance to low output impedance, allowing the use of a longer extension cable. The advantage is that the background noise is low and it hardly causes a load on the microphone. It supports the TEDS function and reduces test time. The compact design enables it to measure in environments with limited space.
